Netherlands + swings = Your battery charges.
There are many ways to recharge a mobile, but this is one of the most fun!
As we increasingly depend on batteries, we must find new ways to recharge our phones, wireless headphones, smart watches, etc. But what do you think of the idea of recharging your cell phone while you swing?
Yes, that's Play for Power, a swing that recharges your mobile when you use it.
The idea is from the advertising agency ID310, at the request of the Dutch Railways. In the Central Station of Utrecht, in the Netherlands, swings have been installed that recharge the mobile while you wait for your train to arrive.
Its operation is very simple: you just have to connect the mobile to a USB port connected to a generator. The swing seats have straps connected to gears that move when the seat swings. These gears generate kinetic energy that activates a generator that transmits electricity to the mobile battery.
Most likely, it will take a few hours to recharge the mobile to 100% using this system, but that is the least of it. The important thing here is that you have fun on the swing while you wait for the train, and when you leave, the battery of your mobile has been recharged with your own effort.
I think it is a brilliant idea … the only one but it is Covid, but we are already fighting against it.
